Image-based 3D target detection method and system, medium and program product

The invention discloses an image-based 3D target detection method and system, a medium and a program product, and the method comprises the steps: obtaining an image containing annotation information, and extracting the training information of the image containing annotation information, the training information at least comprising category information and 2.5 D target frame attribute information; obtaining a first deep learning network model and a corresponding pre-training weight, wherein the first deep learning network model at least can obtain position information and category information of the 2D target frame; generating a second deep learning network model on the first deep learning network model based on the 2.5 D target frame attribute information; loading the pre-training weight as an initial weight of the second deep learning network model, and training the second deep learning network model to obtain a 2.5 D target frame; and converting the 2.5 D target frame into a 3D target frame for 3D target de
